Dismantling was a little difficult, because the snap ring was soooo tight. (Our snap ring pliers aren't the best.) We also bought gear grease and a new gearcase housing. Unfortunately, we didn't realize that the housing had broken until we were removing the old gasket. Once we had all the parts, it was basically a plug and play set up, aside from the snap ring, lol. I really appreciated the schematics that this website supplies. It helped us to know what parts to order.

I used it to make bread - it worked like a dream :)

Easy ; remove belt ( 1 screw ) remove cover , and there is the complete drive . I still need the top plastic cover which is cracked and broken where the bolts go through . Please quote this part .Conradt

Remover screws from top. Used snap ring pliers to remove snap ring replaced gear and reassemblied.

Taking apart the machine is really easy. I was worried the grease would have spilled all over the places, but when the machine is cool, the grease is solid, so no spill. Replace the parts is quite straightforward, and there are plenty of tutorials on line. The only tip is that the grease used by KitchenAid is dark, and it is not easy to see all the small parts when you take the gearbox apart, so pay attention at what you do and at what you throw away... when I got to put it back together I missed a special concave washer which must have been trapped in the grease. Other than that... it has been an easy repair, the mixer is back up and running and I saved a ton on $$$

Replaced cracked plastic gearcase/transmission with new medal one and replaced hub bevel gear attachment, bevel gear and gasket.
